FREDERICK M. WHYTE, OF TARRYTOWN, NEW YORK,v ASSIGNOR TO HUTCI-IINS CARROOFING COMPANY, 0F DETROIT. MICHIGAN, A CORPORATION OF lVIICI-IIGAN.

CAR-ROOF.

Specification of Letters Patent.

Patented Dee. 5, 1916.

Application filed October 13, 1913. Serial No. 794,978.

To all whom t may concern Be it known that I, Fnnnnnioii MViir'rn, acitizen of the United States of America, residing at rTarrytown, in thecounty of festchester and State of New York, have invented certain newand useful Improvements in Car-Roofs, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention relates to car roofs of the type comprising a series ofseparate roofing plates which are independently movable and have weatherproofing connections.

Various constructions have heretofore been devised in which the roofingplates are flexibly supported upon carlines. lVith the presentconstruction the plates are rigidly secured to the carlines, but areflexible in relation to each other, the flexible connec tions being alsoweather proof.

In the drawings: Figure l is a longitudinal section through a portion ofthe car roof intermediate the ridge and eaves; Fig. 2 is a section inthe plane of the ridge purlin; Fig. 3 is a transverse cross sectionthrough a roofing-sheet; and Fig. #l is a view similar to Fig. l,showing a modification.

A is a carline for si'lpporting the roof structure` and which, as shownin Fig. l, is of a U-shaped cross section having out- 'ardly-extcndingflanges B.

C are the roofing plates extending transversely of the car, preferablyfrom cave to eave.

Instead of arranging the sheets C to extend from carline to carline, asis the more usual practice, these plates are supported intermediate thesides of the sheets upon the carline and are preferably rigidly attachedthereto by riveting the flanges B to the plates as indicated at I). Theedges of adjacent plates are, however, free from each other so as topermit of the independent movement and the flexing of the roofstructure. A weather-proof joint between the plates is obtained bysuitable weather-proofing means, such as U-shaped caps E embrao ing theopposite flanges F at the edges of the sheets, said caps being alsopreferably provided with laterally-extending flanges G.

lith the construction as described, each of the plates C is rigid inrelation to the particular carline upon which it is supported, but theflexible weatherproof joint between adjacent sheets permits of freerelative movement thereof to compensate for weaving of the car fralne.

In Fig.l il, a .modified construction is shown, in which the carline Ais arranged above the sheet C and is riveted or otherwise rigidlvsecured thereto. The construction is otherwise sin'iilar to that shownin Fig. l, the edges of the sheets being provided with similarweather-proofing means.

As the roofing plates are rigidly attached to the cai-lines it isunnecessary to provide any other means of securing them to the car, andto obtain greater flexibility, the down-turned flanges Il at the eavesare slightly spaced from the fascia of the car so as to permit freedomof movement. The arrangement of the carlincs intermediate the sides ofthe sheet also .increases the strength of the latter and avoids thenecessity of intermediate support by purlins. If

desired, however, a rigid purlin I may be' used, which, as shown in Fig.2, is formed of a metallic beam having flattened portions .l forattachment to the carlines and intermediate depressed portions K. Therunning board L may be secured by brackets lVI which are secured byrivets N to the roofing-- plates and ridge-purlin.

The weather-proofing caps E preferably extend from cave to cave and aresecured in position by bolts f) which pass between the upstandingflanges lf. These bolts mav be rigidly attached to the caps, as by ashoulder l beneath the cap and riveted head Q thereabove. The bolts aresecured to the underside of the plates by clips R, which are detachablvsecured to the bolt Shanks by suitable means, such as wedge-keys S.

IVhat I claim as my invention is.:

l. A car roof, comprising a series of roofing plates, cai-lines to whichsaid plates are rigidly secured, and weather-proofing connection betweenadjacent plates permitting freedom of relative movement.

A car roof, comprising a series of carlines, roofing plates rigidlysupported upon said carlines and otherwise free from the car and fromeach other, and weather proof* ing means between said plates.

3. A car roof, comprising a series of carlines, roofing plates rigidlysupported intermediate their edges upon the respective carlines andhaving upstanding marginal flanges free from each other, a ruiming boardsupported upon said plates above said oarlines, and a Weather-proofingcap for said npstanding flanges extending from eave to eave and beneathsaid running board.

4. A cai' roof, comprising a series of interinediately ti'ussed andintermediately, rigidly supported roofing plates extending from eave toeave, and ieXible Weatherprooiing means between adjacent edges of saidplates.

5. In a oar roof, the combination With intermediately supported adjacentroofing plates extending from eave to eave, 'upstanding flanges at theadjacent edges of said plates, caps embracing said Hang'es extendingfrom eave to eave, and securing means for said caps extending betweensaid anges.

In testimony whereof I ailix my signature in presence of two witnesses.
